AUTOMATIC CUT-OFF FOR BONE-BLACK KILNS.

SPECIFICATION forming part of Letters Patent No. 264,337, dated September 12, 1882.

Application filed May 20, 1882. (No model.) I

To all whom it may concern:

Be it known that we, GYRUs T. RAYNER and RICHARD STENHoUsE, both of- N ew Orleans, in the parish of Orleans and State of Louisiana, have invented a new and Improved Automatic Out-0ft for Bone-Black'Kilns, of which the following is a full, clear, and exact description.

The object of our invention is to provide for operating the cut-off of bone-blackkilns used in sugar-houses by mechanism requiring but little power for its operation, and which shall be reliable in its operation.

To that end our invention consists in a regulating-plate and a cut-off roller operated by an endless chain for drawing the coolers at intervals, as required, as hereinafter described and claimed. I

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of a kiln provided with our automatic cut-off mechanism. Fig. 2 is a transverse section on line as a: of Fig.1; and Fig. 3 is a detail view.

A is one of the supporting-columns of the kiln.

B B are the coolers, which are placed in'two rows, as usual, supported upon base-plates a, which are suspended by rods 11 from the kilnbottom. On plates a are hangers I), supportin g cross-shafts h. Upon the shafts h are the cnt-ofl' rollers K K, which rollers extend beneath the coolers B, and upon the shafts at the end of the rollers K are wheels Z i, that are provided with pins in for giving rotation to the rollers K, as hereinafter described.

On studs 71/, projecting from longitudinal side bars, z, attached to columns A, are loose chain or sprocket wheels n, which are rotated by an endless chain, 0, the chain'o being operated by a pulley on the driving-shaft 19.

q q are side lugs or projections upon the chain 0, placed at regular intervals and at any required distance apart, for giving rotation to the wheel I, by contact with the pins mthereon.

The coolers B are provided each with an aperture in the bottom above the roller K, and from this aperture extends a pipe having a side opening, 1'. Each cooler is also provided with a regulating-plate, 8, formed with a lip or flange, s, and adjustable by set-screws t, so that the flange of the plate may be moved up or down to cover the discharge-openin g 0" moreor less, the object being to regulate the discharge, it being necessary to give the middle retorts of the kiln a more rapid discharge, as they will burn more matter than the outside retorts.

In operation the chain 0 is to be speeded so that it will travel its own length in a certain interval of time. If it is desired to give the roller'K a full turn in each length of the chain,

the chain will be provided with four pins, q,

or for a half-turn with two pins, each pin acting to give to the roller K of each row of coolers a quarter-rotation. This arrangement provides for drawing the coolers at regular intervals of time, and by adjustment of the regulating-plate for drawing a given quantity, so

that a given quantity can be drawn in a given time without varying the speed or power. As the rollers K turn they carry out a certain quantity of the bone-black, the amount being more or less according to the adjustment of the plate 8.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. In bone-black kilns, the rollers K, fitted beneath the coolers B, and the endless chain 0, operating to give the rollers K a partial rotation at regular intervals, substantially as described, combined for operation, as set forth.

2. The combination of the rollers K, the wheels l, provided with pins on, and the endless chain o, provided with pins q, together and with the coolers B, having outlet-openings r, substantially as shown and described.

3. The adjustable regulating-plate s, in combination with the coolers B, having outlets r, and the rollers K, substantially as shown and described.

4. In bone-black kilns, two or more cut-01f rollers, K K, combined with an endless travelin g chain, 0, substantially as described, whereby both rollers are operated by a single chain.
